現參看形成本發明之一部分的附圖。 Reference is now made to the accompanying drawings which form a part of the invention.
現將參看圖式來解釋選定之實施例。熟習此項技術者自本發明將顯而易見的是，僅出於說明而非出於限制如由隨附申請專利範圍及其等效物界定之本發明的目的來提供實施例之以下描述。 The selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art that the present invention is described by way of the description of the invention.
最初參看圖1至圖3，說明根據第一實施例之自行車傳動鏈條10之部分。當在本文中用以描述自行車傳動鏈條10之零件時，以下方向術語「內側」、「外側」、「內部」、「外部」、「在...之上」、「在...之下」、「寬度」及「縱向」以及任何其他類似方向術語指代相對於處於在水平表面上直立之自行車上的安裝位置中的自行車傳動鏈條10之彼等方向。自行車傳動鏈條10基本上包括：複數個外部鏈片12、複數個內部鏈片14及複數個連接銷16與複數個滾子18。外部鏈片12、內部鏈片14、連接銷16及滾子18為自行車鏈條領域中熟知的金屬零件。滾子18安置在鏈條連接銷16上以 在鏈條連接銷16上旋轉。因為外部鏈片12、內部鏈片14、鏈條連接銷16、滾子18為熟知結構，所以除了視需要用來解釋自行車傳動鏈條10之建構之外，在本文中將不會對其進行詳細論述及/或說明。當然，熟習此項技術者自本發明將顯而易見的是，此等零件可視必需及/或視需要而變化。 Referring initially to Figures 1 through 3, portions of a bicycle drive chain 10 in accordance with a first embodiment are illustrated. When used herein to describe a part of a bicycle drive chain 10, the following directions are used to mean "inside", "outside", "inside", "outside", "above", "under" The terms "width" and "longitudinal" and any other similar directional terms refer to the direction of the bicycle drive chain 10 relative to the mounting position on the bicycle that is upright on a horizontal surface. The bicycle transmission chain 10 basically includes a plurality of outer chain pieces 12, a plurality of inner chain pieces 14 and a plurality of connecting pins 16 and a plurality of rollers 18. The outer chain piece 12, the inner chain piece 14, the connecting pin 16, and the roller 18 are metal parts well known in the bicycle chain art. The roller 18 is placed on the chain connecting pin 16 to Rotate on the chain connecting pin 16. Since the outer chain piece 12, the inner chain piece 14, the chain connecting pin 16, and the roller 18 are well-known structures, they will not be discussed in detail herein except as needed to explain the construction of the bicycle transmission chain 10. And / or instructions. Of course, it will be apparent to those skilled in the art from this disclosure that such parts may be as necessary and/or varied as desired.
如最佳在圖3中所見，為了形成單個連續鏈環，一對末端外部鏈片12及一對末端內部鏈片14由鏈條連接銷16A連接在一起。鏈條連接銷16A為實心銷，其以不同於鏈條連接銷16之方式安裝，如下文所論述。類似於鏈條連接銷16，滾子18中之一者亦安置在鏈條連接銷16A周圍。鏈條連接銷16被說明為中空圓柱體，在每一末端具有漸縮部分，以使得鏈條連接銷16可容易在每一末端變形。然而，視必需及/或視需要，連接銷16可為實心銷。 As best seen in Figure 3, to form a single continuous link, a pair of end outer links 12 and a pair of end inner links 14 are joined together by a chain link pin 16A. The chain connecting pin 16A is a solid pin that is mounted in a manner different from the chain connecting pin 16, as discussed below. Similar to the chain connecting pin 16, one of the rollers 18 is also disposed around the chain connecting pin 16A. The chain connecting pin 16 is illustrated as a hollow cylinder having a tapered portion at each end so that the chain connecting pin 16 can be easily deformed at each end. However, the connecting pin 16 can be a solid pin, as necessary and/or as needed.
如在圖3中所見，外部鏈片12中之每一者具有用於收納鏈條連接銷16或16A之一對銷開口12a。類似地，內部鏈片14中之每一者具有用於各自收納鏈條連接銷16或16A中之一者的一對銷開口14a。內部鏈片14具有形成銷開口14a之整合式(型鍛式)襯套。當然，視必需及/或視需要，可使用獨立襯套。基本上，外部鏈片12之內部端面重疊在內部鏈片14之外部端面上，其中銷開口12a及14a中之各別者對準。接著，首先，將鏈條連接銷穿過銷開口12a及14a而***，以便將內部鏈片14及外部鏈片12彼此連接以形成具有指定長度的細長鏈條。最終，於是將鏈條連接銷16A用於 將該對末端外部鏈片12及該對末端內部鏈片14互連在一起以形成連續鏈環。因此，每一對相對的外部鏈片12由鏈條連接銷16中之兩者或鏈條連接銷16中之一者及鏈條連接銷16A連接在一起以形成外部鏈節。同樣，每一對相對的內部鏈片14由鏈條連接銷16中之兩者或鏈條連接銷16中之一者及鏈條連接銷16A連接在一起以形成內部鏈節。以習知方式透過鏈條連接銷16及16A將內部鏈片14與外部鏈片12以交替之方式互連。因此，外部鏈片12相對於自行車傳動鏈條10之中心縱向平面配置於內部鏈片14之外側。 As seen in Figure 3, each of the outer links 12 has a pair of pin openings 12a for receiving the chain connecting pins 16 or 16A. Similarly, each of the inner links 14 has a pair of pin openings 14a for receiving one of the chain connecting pins 16 or 16A, respectively. The inner link 14 has an integrated (forged) bushing that forms a pin opening 14a. Of course, separate bushings may be used as needed and / or as needed. Basically, the inner end faces of the outer links 12 are superposed on the outer end faces of the inner links 14, wherein the respective ones of the pin openings 12a and 14a are aligned. Next, first, the chain connecting pin is inserted through the pin openings 12a and 14a to join the inner chain piece 14 and the outer chain piece 12 to each other to form an elongated chain having a specified length. Finally, the chain connecting pin 16A is then used for The pair of end outer links 12 and the pair of end inner links 14 are interconnected to form a continuous link. Thus, each pair of opposing outer links 12 are joined together by one of the chain link pins 16 or one of the chain link pins 16 and the chain link pins 16A to form an outer link. Likewise, each pair of opposing inner links 14 are joined together by one of the chain link pins 16 or one of the chain link pins 16 and the chain link pins 16A to form an internal link. The inner chain 14 and the outer chain 12 are interconnected in an alternating manner through the chain connecting pins 16 and 16A in a conventional manner. Therefore, the outer chain piece 12 is disposed on the outer side of the inner chain piece 14 with respect to the central longitudinal plane of the bicycle transmission chain 10.
在將鏈條連接銷16A安裝至外部鏈片12及內部鏈片14之前，鏈條連接銷16A包括銷本體20、***部分22及連接部分24。連接部分24定位於銷本體20與***部分22之間。因此，連接部分24將銷本體20及***部分22互連。 The chain connecting pin 16A includes a pin body 20, an insertion portion 22, and a connecting portion 24 before the chain connecting pin 16A is attached to the outer chain piece 12 and the inner chain piece 14. The connecting portion 24 is positioned between the pin body 20 and the insertion portion 22. Therefore, the connecting portion 24 interconnects the pin body 20 and the insertion portion 22.
在圖6所說明之一個較佳實施例中，銷本體20、***部分22及連接部分24係彼此整體地形成。較佳地，鏈條連接銷16A較佳由硬質剛性材料(諸如，已知用於製造自行車鏈條之金屬材料)形成為整片單一構件。舉例而言，鏈條連接銷16A可由鎳鉻鉬鋼製成。較佳地，鏈條連接銷16A經受表面硬化處理以改良抗磨性。 In a preferred embodiment illustrated in Figure 6, the pin body 20, the insertion portion 22 and the connecting portion 24 are integrally formed with one another. Preferably, the chain connecting pin 16A is preferably formed as a single piece from a rigid rigid material such as a metal material known for use in the manufacture of bicycle chains. For example, the chain connecting pin 16A may be made of nickel chrome molybdenum steel. Preferably, the chain connecting pin 16A is subjected to a surface hardening treatment to improve abrasion resistance.
隨著銷本體20被強制性地***穿過一對外部鏈片12之銷開口12a及內部鏈片14之一對銷開口14a，銷本體20實際上用於外部鏈片12與內部鏈片14之間的連接。***部分22用於在製造自行車傳動鏈條10之組裝製程期間初始地導引鏈條連接銷16A穿過該對外部鏈片12及內部鏈片14之該對銷 開口14a。 As the pin body 20 is forcibly inserted through the pin opening 12a of the pair of outer chain pieces 12 and one of the pair of inner chain pieces 14 to the pin opening 14a, the pin body 20 is actually used for the outer chain piece 12 and the inner chain piece 14 the connection between. The insertion portion 22 is for initially guiding the chain connecting pin 16A through the pair of pins of the pair of outer chain pieces 12 and the inner chain piece 14 during the assembly process of manufacturing the bicycle transmission chain 10. Opening 14a.
如下文所解釋，連接部分24經組態以在銷本體20安裝於自行車傳動鏈條10之一對鄰近鏈節之間後自銷本體20切斷且保持附接至***部分22。較佳地，銷本體20、***部分22及連接部分24係彼此整體地形成。連接部分24較佳具有小於銷本體20及***部分22之最大直徑。 As explained below, the connecting portion 24 is configured to be severed from the pin body 20 and remains attached to the insertion portion 22 after the pin body 20 is mounted between one pair of adjacent bicycle links of the bicycle transmission chain 10. Preferably, the pin body 20, the insertion portion 22, and the connecting portion 24 are integrally formed with each other. The connecting portion 24 preferably has a smaller diameter than the pin body 20 and the insertion portion 22.
銷本體20具有第一軸向端面31及第二軸向端面32。在組裝傳動鏈條10時，銷本體20具有略大於外部鏈片12之間的橫向距離的長度。銷本體20之第一軸向端面31包括凹陷33。較佳地，銷本體20之第一軸向端面31之凹陷33為圓錐狀的。凹陷33可用於收納用於將銷本體20安裝至一對鄰近鏈節中之工具。第二軸向端面32具有關於第二軸向端面32之最外邊緣35的凹陷表面34。如在圖7及圖8中所見，凹陷表面34較佳包括漸縮部分34a，隨著漸縮部分34a在自第二軸向端面32之最外邊緣35朝向銷本體20之中心軸線之方向上延伸，漸縮部分34a隨著靠近第一軸向端面31而漸縮。雖然在所說明之實施例中，整個凹陷表面34由漸縮部分34a形成，但視必需及/或視需要，凹陷表面34可具有非漸縮部分。 The pin body 20 has a first axial end surface 31 and a second axial end surface 32. When assembling the drive chain 10, the pin body 20 has a length that is slightly larger than the lateral distance between the outer links 12. The first axial end face 31 of the pin body 20 includes a recess 33. Preferably, the recess 33 of the first axial end face 31 of the pin body 20 is conical. The recess 33 can be used to receive a tool for mounting the pin body 20 into a pair of adjacent links. The second axial end face 32 has a recessed surface 34 with respect to the outermost edge 35 of the second axial end face 32. As seen in Figures 7 and 8, the recessed surface 34 preferably includes a tapered portion 34a as the tapered portion 34a is in a direction from the outermost edge 35 of the second axial end surface 32 toward the central axis of the pin body 20. Extending, the tapered portion 34a tapers as it approaches the first axial end face 31. Although in the illustrated embodiment, the entire recessed surface 34 is formed by the tapered portion 34a, the recessed surface 34 can have a non-tapered portion as necessary and / or as desired.
在所說明之實施例中，銷本體20進一步包括中央圓柱形部分40、第一凸緣41及第二凸緣42。銷本體20之中央圓柱形部分40具有大於***部分22之最大外徑或寬度之最大外徑。中央圓柱形部分40較佳形成有兩個圓柱形區段40a及40b。圓柱形區段40a可具有略大於圓柱形區段40b之直 徑。圓柱形區段40a及40b兩者可具有大於***部分22之最大外徑或寬度之最大外徑。圓柱形區段40a具有略大於銷開口12a之直徑的直徑。圓柱形區段40a之軸向長度較佳約等於外部鏈片12之厚度。 In the illustrated embodiment, the pin body 20 further includes a central cylindrical portion 40, a first flange 41, and a second flange 42. The central cylindrical portion 40 of the pin body 20 has a maximum outer diameter that is greater than the largest outer diameter or width of the insertion portion 22. The central cylindrical portion 40 is preferably formed with two cylindrical sections 40a and 40b. The cylindrical section 40a can have a diameter that is slightly larger than the cylindrical section 40b path. Both cylindrical sections 40a and 40b can have a largest outer diameter that is greater than the largest outer diameter or width of the insertion portion 22. The cylindrical section 40a has a diameter slightly larger than the diameter of the pin opening 12a. The axial length of the cylindrical section 40a is preferably approximately equal to the thickness of the outer link 12.
第一凸緣41安置為鄰近於第一軸向端面31，而第二凸緣42安置為鄰近於第二軸向端面32。因此，第一凸緣41及第二凸緣42安置於中央圓柱形部分40之相反的縱向末端處，以防止銷本體20無意中滑出銷開口12a。第二凸緣42包括部分球形表面42a，其自第二軸向端面32之最外邊緣35在徑向向外之方向上延伸。部分球形表面42a輔助將銷本體20***至銷開口12a及14a中。 The first flange 41 is disposed adjacent to the first axial end face 31 and the second flange 42 is disposed adjacent to the second axial end face 32. Accordingly, the first flange 41 and the second flange 42 are disposed at opposite longitudinal ends of the central cylindrical portion 40 to prevent the pin body 20 from inadvertently sliding out of the pin opening 12a. The second flange 42 includes a partially spherical surface 42a that extends in a radially outward direction from the outermost edge 35 of the second axial end surface 32. The partially spherical surface 42a assists in inserting the pin body 20 into the pin openings 12a and 14a.
將更詳細地論述連接部分24。可藉由環形切割銷本體20之第二凸緣42與***部分22之間的鏈條連接銷16A之中間周邊區段而形成連接部分24。因此，連接部分24相對於銷本體20及***部分22具有減小之直徑，以使得可藉由將剪切力施加至***部分22而容易地將部分3與銷本體20分離。此外，連接部分24具有較佳略短於外部鏈片12之厚度的軸向長度，以便促進將***部分22***至銷開口12a中。 The connecting portion 24 will be discussed in more detail. The connecting portion 24 can be formed by the intermediate peripheral section of the chain connecting pin 16A between the second flange 42 of the annular cutting pin body 20 and the insertion portion 22. Therefore, the connecting portion 24 has a reduced diameter with respect to the pin body 20 and the insertion portion 22, so that the portion 3 can be easily separated from the pin body 20 by applying a shearing force to the insertion portion 22. Further, the connecting portion 24 has an axial length preferably slightly shorter than the thickness of the outer chain piece 12 to facilitate insertion of the insertion portion 22 into the pin opening 12a.
連接部分24較佳由易碎連接件50附接至銷本體20之第二軸向端面32之凹陷表面34。易碎連接件50構成銷本體20與連接部分34之間的剪切線，在***部分22折斷時，連接部分24在該剪切線處自銷本體20剪切開。連接部分24較佳為截頭圓錐狀的，以使得易碎連接件50位於形成第二軸向端 面32之平面之下。換言之，連接部分24具有小直徑末端51及大直徑末端52。小直徑末端51在易碎連接件50處附接至銷本體20之凹陷表面34。大直徑末端51附接至***部分22。連接部分24相對於銷本體20及***部分22具有減小之直徑。連接部分24具有較佳等於或小於一毫米之軸向長度。 The attachment portion 24 is preferably attached to the recessed surface 34 of the second axial end surface 32 of the pin body 20 by a frangible link 50. The frangible link 50 constitutes a shear line between the pin body 20 and the connecting portion 34, and when the insertion portion 22 is broken, the connecting portion 24 is sheared from the pin body 20 at the shear line. The connecting portion 24 is preferably frustoconical such that the frangible connector 50 is located at the second axial end. Below the plane of face 32. In other words, the connecting portion 24 has a small diameter end 51 and a large diameter end 52. The small diameter end 51 is attached to the recessed surface 34 of the pin body 20 at the frangible connection 50. The large diameter end 51 is attached to the insertion portion 22. The connecting portion 24 has a reduced diameter with respect to the pin body 20 and the insertion portion 22. The connecting portion 24 has an axial length preferably equal to or less than one millimeter.
現將更詳細地論述***部分22。如上所提及，***部分22附接至連接部分24(亦即，在所說明之實施例中，整體形成)。***部分22較佳包括圓柱形部分60及變窄尖端部分61。圓柱形部分60在連接部分24與變窄尖端部分61之間軸向延伸。隨著變窄尖端部分61在背離連接部分24而朝向銷本體20之中心軸線A之方向上延伸，變窄尖端部分61變窄。 The insertion portion 22 will now be discussed in more detail. As mentioned above, the insertion portion 22 is attached to the connection portion 24 (i.e., integrally formed in the illustrated embodiment). The insertion portion 22 preferably includes a cylindrical portion 60 and a narrowed tip portion 61. The cylindrical portion 60 extends axially between the connecting portion 24 and the narrowed tip portion 61. As the narrowed tip portion 61 extends in a direction away from the connecting portion 24 toward the central axis A of the pin body 20, the narrowed tip portion 61 is narrowed.
參看圖9至圖11，現將更特定地描述使用具有上述建構之鏈條連接銷16A進行之鏈條連接操作。通常，在鏈條連接操作中，銷安裝工具70被用於將鏈條連接銷16A安裝至外部鏈片12之銷開口12a及內部鏈片14之銷開口14a中。如在圖11中所見，銷安裝及移除工具70具有搖架72，其用於在鏈條連接銷16A之安裝期間固持傳動鏈條。銷安裝及移除工具70進一步具有驅動銷74，其可移動地安裝至搖架72以進行軸向移動。通常，驅動銷74具有螺紋部分，其擰旋至搖架72之螺紋孔中，以使得驅動銷74之旋轉引起驅動銷74軸向移動。較佳地，驅動銷74在其一端具有把手76，其用於相對於搖架72而旋轉驅動銷72。銷安裝及移除工具 (諸如，所說明之銷安裝及移除工具)為熟知的，且因此，在本文中將不會詳細論述及/或說明銷安裝及移除工具70。 Referring to Figures 9 through 11, the chain connecting operation using the chain connecting pin 16A having the above construction will now be described more specifically. Generally, in the chain connecting operation, the pin mounting tool 70 is used to mount the chain connecting pin 16A to the pin opening 12a of the outer chain piece 12 and the pin opening 14a of the inner chain piece 14. As seen in Figure 11, the pin mounting and removal tool 70 has a cradle 72 for retaining the drive chain during installation of the chain link pin 16A. The pin mounting and removal tool 70 further has a drive pin 74 that is movably mounted to the cradle 72 for axial movement. Typically, the drive pin 74 has a threaded portion that is threaded into the threaded bore of the cradle 72 such that rotation of the drive pin 74 causes the drive pin 74 to move axially. Preferably, the drive pin 74 has a handle 76 at one end thereof for rotationally driving the pin 72 relative to the cradle 72. Pin installation and removal tool (such as the illustrated pin mounting and removal tool) are well known and, therefore, the pin mounting and removal tool 70 will not be discussed and/or illustrated in detail herein.
首先，為了連接斷開之鏈條之自由末端，將外部鏈片12之內部端面重疊在內部鏈片14之外部端面上，其中使銷開口12a及14a彼此對準。在此條件下，將***部分22***穿過第一對銷開口12a及14a且接著穿過第二對銷開口12a及14a，如圖9中所見。取決於相對銷開口12a及14a之直徑的***部分22之最大直徑，此可用手或藉由使用驅動銷74來進行。在任何情況下，推動銷本體20之第一軸向端面31，以使得***部分22安置於銷開口12a及14a中，如圖9中可見。接著，如圖9及圖10中可見，將驅動銷74用以將銷本體20***至銷開口12a及14a中，以使得第一凸緣41及第二凸緣42嚙合外部鏈片12之外部端面。 First, in order to connect the free ends of the broken chain, the inner end faces of the outer links 12 are superposed on the outer end faces of the inner links 14, wherein the pin openings 12a and 14a are aligned with each other. Under this condition, the insertion portion 22 is inserted through the first pair of pin openings 12a and 14a and then through the second pair of pin openings 12a and 14a, as seen in FIG. Depending on the maximum diameter of the insertion portion 22 relative to the diameter of the pin openings 12a and 14a, this can be done by hand or by using the drive pin 74. In any event, the first axial end face 31 of the pin body 20 is urged such that the insertion portion 22 is disposed in the pin openings 12a and 14a as seen in FIG. Next, as seen in Figures 9 and 10, the drive pin 74 is used to insert the pin body 20 into the pin openings 12a and 14a such that the first flange 41 and the second flange 42 engage the exterior of the outer link 12. End face.
如在圖10中可見，一旦銷本體20安置於銷開口12a及14a中，***部分22實質上完全自外部鏈片12突出。接著，將此突出之***部分22配合至銷安裝及移除工具70之收納孔78中，且相對於傳動鏈條10扳動銷安裝及移除工具70。因此，在易碎連接件50處，連接部分24自銷本體20剪切開。因為連接部分24附接至銷本體20之凹陷表面34，所以剩餘連接部分在鏈條連接操作完成後不會自銷本體向外突起，以便防止剩餘連接部分與其他組件(諸如，鏈輪、變速器等)之不良接觸。最終，視必需，可將傳動鏈條10重新安裝至銷安裝及移除工具70中，以使第二凸緣42變形，以較 緊固地固定鏈條連接銷16A。 As can be seen in Figure 10, once the pin body 20 is disposed in the pin openings 12a and 14a, the insertion portion 22 substantially completely protrudes from the outer chain piece 12. Next, the protruding insertion portion 22 is fitted into the receiving hole 78 of the pin mounting and removal tool 70, and the pin mounting and removal tool 70 is pulled relative to the drive chain 10. Thus, at the frangible link 50, the connecting portion 24 is sheared away from the pin body 20. Since the connecting portion 24 is attached to the recessed surface 34 of the pin body 20, the remaining connecting portion does not protrude outward from the pin body after the chain connecting operation is completed, in order to prevent the remaining connecting portion from other components (such as a sprocket, a transmission, etc.) ) bad contact. Finally, the drive chain 10 can be reinstalled into the pin mounting and removal tool 70 as necessary to deform the second flange 42 to The chain connecting pin 16A is fixedly fastened.
在前述實施例中，***部分22形成有圓柱形部分60及變窄尖端部分61。此***部分22可改為具有不同組態。舉例而言，可預期形成具有漸縮形狀之整個***部分22。此***部分22之長度亦不限於前述實施例中所述之長度。 In the foregoing embodiment, the insertion portion 22 is formed with a cylindrical portion 60 and a narrowed tip portion 61. This insertion portion 22 can instead have a different configuration. For example, it is contemplated to form the entire insertion portion 22 having a tapered shape. The length of the insertion portion 22 is also not limited to the length described in the foregoing embodiment.
